Integration of modern SD-WAN with SASE can improve the security architecture. However, the path to achieving this can be complex and challenging.
Organizations are accelerating the development of their security architecture due to the continued adoption of the cloud and hybrid work structures. Secure Access Service Edge (SASE), which integrates security and networking capabilities to enhance performance and provide better security outcomes, is being adopted with SD-WAN deployments more frequently. However,
Infrastructure leaders are having trouble aligning their SD-WAN initiatives with SASE ones. Infrastructure leaders are unable to create a completely converged SASE framework due to a lack of tight integration with security services, which raises security risks, and causes network outages, and costs.
In addition, customers have built multi-vendor solutions by patching together different solutions in order to provide a SASE solution, which has added cost and complexity. By forcing security and networking teams to handle different policy structures and frameworks, this piecemeal approach hinders effective collaboration and increases operational complexity. Organizations need a dependable and seamless transition to a single-vendor solution that utilizes a next-generation SD-WAN consisting of native integration to cloud-delivered security services in order to reap the full benefits of SASE.
Strategies for Successful SASE Migration
Infrastructure leaders must develop a successful SASE migration plan while minimizing the chance of implementing a security architecture that is less than ideal. When assessing security services and SD-WAN together, they should consider the following capabilities that can greatly ease their migration approach, including:
Dependable Links to Security Services
To supply features like a Cloud Access Security Broker (CASB), Secure Web Gateway (SWG), and Firewall as a Service (FWaaS), which increase operational complexity and expenses, IT managers are compelled to establish connections to numerous security services manually. Simple and fully automated connections to these security services that offer high availability and redundancy should be made possible by SD-WAN solutions.
Adopt Zero Trust
Zero trust architectures typically employ a “set and forget” strategy that, once access is granted, implicitly trusts applications always, leading to malicious activity during an authorized activity. Security services that enable Zero Trust with least-privileged access and ongoing trust verification for all applications and users should seamlessly integrate with SD-WAN solutions.
Scalable Security Services
The challenges of handling multiple Points of Presence (POPs) and ensuring they are properly positioned to secure and enhance application performance is a constant source of frustration for IT professionals. For improved uptime and lower application latency, businesses should embrace SD-WAN that links to security services that have a global presence across all geographic regions at scale.
SLAs for Asset Applications
Inaccurate selection of POPs/ cloud gateway based on network and application SLAs by legacy SD-WAN solutions results in subpar performance and possible outages.
Encourage Flexible Usage of Services
A flexible consumption architecture that enables enterprises to smoothly allocate bandwidth among branch offices from an aggregated pool should be provided by an SD-WAN solution. When establishing a SASE architecture, which can safeguard data and provide a better user experience, enterprises should be able to extend this consumption model smoothly to security services.
Utilize the Unified Policy Framework to Streamline Operations
Monitoring, configuring, and supporting different policy structures for networking and security is a challenge for organizations attempting to implement SASE. Without a common policy framework, IT teams have to spend a lot of time coordinating apps and policies throughout their network. One of the core features of SD-WAN and SASE cloud-delivered services should use the same data lake and policy framework as secure web gateways, firewall, ZTNA, and CASB, making it simpler to deploy and more effective to operate with few configuration conflicts.
